This character set[9] was different from de oder Braziwian character set, ABICOMP.

The goaw of dis character set was to ewiminate de “Babew’s Tower”[4] of de existing coding systems for de Portuguese wanguage (ISO IR-16, ISO IR-84, IBM 256 , IBM 275, IBM 850, DEC Muwtinationaw, HP Roman-8, Mac OS Roman, etc.). In spite of dat, dis code set had troubwes in imposing itsewf,[2][4] mainwy due to de pressure of big muwtinationaw corporations and finished by being wess and wess used because of de ubiqwity of oder character sets (ISO 8859-1 and water Unicode).

Each character is encoded as a singwe eight-bit code vawue. These code vawues can be used in awmost any data interchange system to communicate in de fowwowing wanguages (wif a few exceptions due to missing characters, as noted):

The wetter ÿ, which appears in French onwy very rarewy, and never at de beginning of words, is incwuded onwy in wowercase form. The swot corresponding to its uppercase form is occupied by de wowercase wetter ß from de German wanguage, which itsewf is rarewy used in its uppercase form.
